3 introduction introduction The Atmospherix and Atmospherix A20 are high quality in-ceiling loudspeakers featuring fully sealed back-boxes to control and maximise bass response, whilst keeping out dust and other ceiling inhabitants. The Atmospherix A20 employs an acoustically optimised front baffle angled at 20 degrees allowing its sound output to be projected towards your primary listening area. The standard Atmospherix employs a flat front baffle for uniform sound coverage in all directions. (figure 1) Atmospherix A20 Atmospherix applications best suited to Amospherix The wide uniform coverage of the Atmospherix makes it the ideal choice for 2 channel stereo and background music applications. Its uniform coverage is ideally suited to any applications where the listening area is not confined to a specific part of the room. For examples, hallways, dinning rooms, office spaces and bedrooms and multipurpose rooms. (figure 2) applications suited to Amospherix A20 The ability of the Atmospherix A20 to project sound toward your listening primary listening area makes it ideally suited to home cinema applications (figure 3). Dialogue will become more articulate, music will have better definition and surround effects will become more involving and realistic. The A20 s ablility to direct more sound towards the listener results in less sound reflecting off walls and other surfaces in the room creating a clearer, more three dimensional soundstage. The A20 may also be useful for background music applications where the speakers must be placed near a side wall for aesthetic or structural reasons. In this application the the A20 can be used to project the sound towards the centre of the room. 500mm recommended minimum figure 1 figure 2 500mm figure 3 3

4 installation before you begin Please read the disclaimer on page 2 of this manual. Refers to page 3 of this manual and discuss with your local Krix distributor, or installation consultant, to determine the best location for your loudspeakers. Be sure to check for any obstructions, such as electrical wiring, plumbing, stud work or air conditioning ducts before commencing the installation. (figure 4) installation Once the correct placement the speakers has been determined, use the cardboard insert marked template (from the internal packing) to trace the required cut-out onto the ceiling/wall. (figure 5) Drill a hole inside the marked cut-out. Using a fine gyprock saw, cut around the inside of the marked cut-out. (figure 6) Remove the circular offcut and insert the speaker to check the hole is the correct size. Enlarge the cut-out if required. If the grille requires painting it is recommended that the grille is painted attached to the speaker after installation. Use a small foam roller with a light coverage of thin paint to avoiding blocking the holes in the grille. figure 4 Also ensure that there is enough ceiling/ wall space to accommodate the speaker enclosure. connecting To ensure optimum performance it is important that your speaker system is connected properly: Turn off all electronic equipment and disconnect from the power point. Follow the connection instructions supplied with your amplifier, CD/DVD, hard disk recorder, video player etc. Install speaker cable in wall or ceiling cavity, or run cable along wall surface. Allow approximately 300mm of excess cable to facilitate loudspeaker installation. Follow the connection instructions supplied with your amplifier to connect the speaker cables to amplifier. Take care to assign the same cable colour or trace to the positive (+) connector on the amplifier as the positive (+) connector on the speaker. Prepare speaker cables for connecting to speakers by neatly stripping cable ends. Atmospherix A20 only: Determine the correct orientation for your speaker. A small arrow embossed in the front baffle marks the direction of the speakers primary coverage. It is recommended that this arrow is aimed towards your primary listening area for best results. (Figure 3, Figure 7) Pull the stripped speaker cable through the ceiling/wall opening. Push and hold down the positive (+) red binding post on the speaker and insert the positive (+) wire through hole in post. Take care to assign the same cable colour or trace to the positive (+) connector on the amplifier, as the positive (+) connector on the speaker. Repeat connection process with the negative (-) black binding post and the negative (-) wire. (Figure 8) Ensure all mounting clamps are swung back against the speaker enclosure (Figure 8), so that the speaker can be easily inserted into the ceiling cut-out. Once the speaker has been located in the ceiling/wall, use a Philips head screwdriver to tighten all mounting screws. As the screws are tightened, the mounting clamps will automatically swing out over the gyprock and clamp the speaker in place. Be careful not to over tighten the screws, as this may strip the clamp, or crush the gyprock surface. (Figure 9) Gently fit the magnetic grille to the front of the speaker housing. (Figure 10) Care should be taken to eliminate loose strands of wire that may be present a short circuit hazard. 4
